Wave solderingSimple Fast Easy
Forming is the most inefficient work in the wave soldering ， and it may cause electrostatic damage and increase mistake probability, also may delay the delivery time the same time.

Manual welding
Manual welding is suitable for both side components are many and SMD part lot ， but THT component is little ； If THT component is many ， Wave soldering(mould) is suggested.
